ELECTRIC HAIR WAVER.

Application filed July 30, 1923. Serial No. 654,632.

To all whom it may concern:

Be it known that 1, ROBERT P. SIMMONS, a citizen of the United States,residing at Cleveland in the county of Cuyahoga and Ohio, have inventeda certain new and useful Improvement in an Electric Hair aver, of whichthe following is a specification.

This invention relates primarily to hair waving implements and JIIIOIBparticularly to the construction of an electrical appliance which may beelectrically heated by a connection with the usual electric lightingSource for imparting artistic and attractive wave formsto the hair.

One ofthe objects of my invention is to provide an electric hairwaverwhich 13 simvple in construction and capable of inexpensive manufactureon a quantityproduction basis.

Another object of my invention is the provision of a heating elementwhich may be deformedfrom a shape in. which it is readily manufacturedinto the shape of the wave hairff, V

A furtlier-"ob'ect of the-invention is to provide a pair oi" plateshaving the shape of the wave forms to be given to the hair,

forms ii'lllcll lt is desired to impart to the which plates maybe fittedtogether with the heating "element between them but so closely relatedto the plates that substantially the entire quantity of heat generatedby the heating element is immediately conducted their temperature to apredetermined degree and maintaining that temperature .e tliciently ingprocess. v .1.

A stillturther objectof my invention is ineans for gently but fir nlypressing different portions of hair from its extremity to a positionclosely adjacent'ithe head against the wave forming plates whereby toimpart an artistic and attractive wave to the hair appealing to theesthetic sense.

Another object of the invention is to pro forming heating element forimparting limited lateral movement to the hair during the period thatpressed against the heated wave forming plates to secure! a French styleof wave in the hair.

Other and further objects of my invention will be pointed out in thefollowing specification and the appended claims with parduring the hairwav- .wound upon the base,

NT orr cs.

ticular reference to the accompanying drawin sin which:

igure 1 is a plan View of the heating element used in the hair waver ofthis invention, the insulation around the heating wires being brokenaway to clearly show the con struction of the element; this view showsthe element in its manufactured shape before it has been deformed to theshape in which it is used in the hair waver; Fig. 2 is a cross sectionalview of the heating elements shown in Fig. 1 before it is deformed tothe shape in which it is employed in the hair waver; Fig. 3 is eperspective view of the heating element with the insulated coveringremoved 'illustrating the slfiipe to which the heating element isdeformedfor use in the hair assembled electric hair waver, the outsideplate of the wave forming portion being broken away toshow the positionof the heating element between the wave forming heated plates; Fig. 5 isa longitudinal cross sectional view through the wave forming plates ofmy electric hair waver taken on line 55 of Fig. 6 which, is a crosssectional View taken laterally through the hair waver heating plates andheating element; Fig. 7 1s a perspective view of my invention havingdetachable means for laterally moving the hair while it is pressed inthewave forming plates for imparting a French wave to the 12111; and Fig. 8is a cross sectional view of the detachable comb-like member positionedat the top of the wave forming plates for laterally inovingtlie hair incertain limits while it is being pressed in the waver.

My invention contemplates forming a heating elemcnton a sheet ofinsulating material which is bent about a mandrel for the purpose ofwinding. After the wire is.

further insulation HEISSUED material" is wrapped around the elementwhich insulates the heating wire from contact with the metallic surfaceshereinafter described. After the heating element is completed it isdeformed, .warped or pressed out ofits original flat shape into anapproximate W shape or a wave form corresponding approximately to a sinewave orthe wavelike form it is desired to impart to the hair. Anextremely thin heating unit'is thus. provided by the process described.I insert this thin unit between apair of me tallic surfacescorrespondingly shaped in wave form tothe form obtained by the heatingelement. The metallic surfaces are uniformly and instantaneously heatedto the hair down into her is pivoted desired temperature substantiallyby conduction. A hollow stem and handle/is ar ranged to support andmanipulatethe hair wave-shaped surface and maintained in tension for aperiod sufiicicntfor it to become .et. in the wave shape of theplatcs.A.

. French style wave may he imparted to the stood by more particularreference predetermined desired temperature.

' between their inner 95 secured firmly in position with respect toforms a protective casing 'plates 6 and hair by employing an attachablecomb-like structure slidably mounted on the middle crest portionof thewave-shape plates in such mannei t'hat heat is conducted to the combfrom the heating element. The comb maybe reciprocated within narrowlimits drawing the hair backward and forward at the crest point the hairbeing firmly secured by the. prongs at the extren'iity of the loops ofthe wave-shapcd plates, preventing the hair from following the action ofthe comb.

My invention will be more clearly under to the drawings in whichreference character 1 designates a mandrelwhich is used in winding theheating element. An asbestos sheet 2 is wrapped around the mandrelforming the core of the heating element. .i\'[1('it or any otherinsulating material may of course be used as a core ll101Ill)l.. \Vhenmica is used slots are cut on each side to prevent the'tiirns of theresistance wire from slip ping whereas in the ease of asbestos the wirebites into the soft asbestos which prevents the turns of the wire. fromslipping and shorting. The. heating wire is wound I on the core 2 andthe leads fixed as indicated at 5. The element is next wrapped withinsulation material 4 such as asbestos which around the heating elementpreventing electrical contact with the metallic sheets 6 and 7 and alsoserving to reduce the heatv developed to a The eating element is nowdeformed "from its flat shape into a. W or approximately sine wave shapeas shown in Fig. 3. Metallic 7 also of wave form are arthe heatingelement inserted ranged with faces and the plate 6 lar Wave imparted tothe wave by operating the comb plate 7 by a turned over edge 8. Themidle or crest portion of the wave-shaped plates. 7 is of a reducedvertical dimension for. a part of its length to enable the-sup i portingstem 10 to be inserted between the.

plates 6 and 7 which stem is provided With a haiidle 11 to facilitatethe manipulation of. the hair waver. The stem and handle are hollow topermit the connection to heatin element at 5 to be extended throu 'h thedevice to the flexible. exterior-conned tion 12. At' a point 141 onsupporting stem 10 l pivot a lever 15 having prongs 16 and 1.7 whichpull the hair down into the crevices vor the extremity of the loopportions of the waver pressing the hair against the crest or middleportion oi the plates and against the walls 18 and 19 of plates 6 and 7.The lever 15 is manipulated by means of a handle 20 which is closed withreference the to handle 1.1 as indicated in dotted lines at 21 when thehair is forced down against the hot plates by means of prongs 16 and 17.

A detachable comb-like. structure. 22 may be provided with aportion-extending ,over the crest portion of the wave-shaped plateswhereby heat is transferred by conduction t to the comb and to theverticalteeth 23. The hair is normally laid over the waveshaped plates,the prongs16 and 17 being raised out of )laee,- wit-lithe strands entering between the several teeth of the comb and then the prongs. 16 and 17closed down pressing the hair against the hot. plates and drawing thestrands tlirough'tlie comb. The prongs 16 and 17 maybe knurled. tofirmly anchor the hair. The comb 22 may then be reeiprogated by movingtrigger 26 on arm, 24 backward and f01WitI(l,'tli0 comb being guidedwith relation to the stem 10 by means of depending members. 25.

hair by"; pressing it against the wave-shaped plates may now be modifiedto a French style .or snake 7 22 within the limits pcrmitted...by thehair being secured in the lowermost portion of the waveshaped' platesu yv v r The arrangement of my electric hair waver is such that the wavermay be moved over e difl'erent parts of the hair and a wavy appearanceimparted to the strands of hair, as desired, moving the waver into closeproximity of the head.
